CC -!- FUNCTION: Critical negative regulator of cardiac hypertrophy and a CC positive inotropic regulator (By similarity). Crucial regulator of CC cellular iron homeostasis and hemoglobin maturation. May play a CC role in regulating the function of the thioredoxin system. Does CC not posses any thyoredoxin activity since it lacks the conserved CC motif that is essential for catalytic activity. {ECO:0000250, CC ECO:0000269|PubMed:23615448}. CC -!- SUBUNIT: Monomer and homodimer; the homodimer is probably linked CC by 2 2Fe-2S clusters that may serve as a redox sensor. The monomer CC interacts with other proteins. Interacts (via N-terminus) with CC PRKCQ/PKC-theta. Interacts (via C-terminus) with CSRP3 (By CC similarity). Interacts with CSRP2 (By similarity). {ECO:0000250}.

Cytoplasm, myofibril, sarcomere, Z CC line {ECO:0000250}. Note=Under the plasma membrane. After PMA CC stimulation, GLRX3 and PRKCQ/PKC-theta translocate to a more CC extended submembrane area. In the Z line, found associated with CC CSRP3 (By similarity). {ECO:0000250}. CC -!- TISSUE SPECIFICITY: Expressed in heart, spleen, testis and, to a CC lower extent, in thymus and peripheral blood leukocytes. Weakly CC expressed in lung, placenta, colon and small intestine. CC -!- DOMAIN: The thioredoxin domain lacks the two redox-active CC cysteines. This strongly suggests that it lacks thioredoxin CC activity. CC -!- MISCELLANEOUS: Silencing of Grx3 in HeLa cells decreases the CC activities of several cytosolic Fe/S proteins, such as ACO1, a CC major component of post-transcriptional iron regulation. As a CC consequence, Grx3-depleted cells show decreased levels of ferritin CC and increased levels of transferrin receptor, features CC characteristic of cellular iron starvation (PubMed:23615448). CC {ECO:0000305|PubMed:23615448}. CC -!- SIMILARITY: Contains 2 glutaredoxin domains. {ECO:0000255|PROSITE- CC ProRule:PRU00686}. CC -!- SIMILARITY: Contains 1 thioredoxin domain. {ECO:0000255|PROSITE- CC ProRule:PRU00691}.
